Accountants? Mind you, I've known a few and they were generally OK.

the appearance of parallel shear bands (Neumann bands), Yes.
Though not specifically Neumann bands (due to impact) but similar in “the rejection of free cementite to the planes it occupies.”

You have to scroll down a bit to get to the quoted part.
Also as part of the welding process slag is often struck off the weld with a welding hammer. So there generally will be impacts to the weld and surrounding area while the material is still hot.
welding hammer
changes respectively destruction of the cementite lamellas in the perlite, Yes
Depending on how the part is cooled, slower cooling tends to anneal the part.
Fragmentation Rate of Cementite Lamellas in Nanopearlite
As noted above a process often involved before manufacturing with the material , to get a baseline crystalline structure and ease, intended, plastic defamation during forming.
hardness increase, Yes
Again depending on how it is cooled.
Rapid cooling locks more of the the perlite and martensite from returning to the austenite structure. IIRC, metallurgy class was almost some 40 years ago and all of my reference books are at home. Also hardening quenching is usually done in oil or also the heating takes place with carbon nearby to provide more carbon for more of the Pearlite Transformation
Pearlite Transformation
Also just using and working a metal part tends to work-harden it over time.
Work hardening
You can flex a wire back and forth until it breaks, that fracture is due to the embrittlement caused by the work-hardening you applied in repeatedly flexing it.
plastic deformation in the micro area (wavy arrangement of the structure parts), Yes
Plastic deformation during welding (from uneven heating and cooling) is a common issue and may even result in a need for the part to be worked back into an adequately functional shape.
Weld Distortion
Arc welding generates a plasma at the bonding area (localized to the electrode tip) which can lead to uneven heating and subsequent cooling of the part. So not only can welding account for all of this, but likewise can just general parts production and stressful in service use, particularly to the point of failure (perhaps even more than one failure if the part had to be welded).
I made no such claim.
You literally claimed to be a scientist. Twice. Largely you just make statements and arguments that would ordinarily require expertise to give them authority, and expect those arguments and statements to be taken at face value even when they are trivially disprovable.
And how does being a scientist have anything at all to do with this topic? This is about current affairs and thus is about reporting news.
Yes, terribly reckless.
But not risking the lives of 250k people.

WikiThe Department for Environment confirmed the nerve agent was delivered "in a liquid form". They said eight sites require decontamination, which will take several months to complete and cost millions of pounds. The BBC reported experts said the nerve agent does not evaporate or disappear over time. Intense cleaning with caustic chemicals is required to get rid of it.[85][86] The Skripals' survival was possibly due to the weather – there had been heavy fog and high humidity, and according to its inventor and other scientists, moisture weakens the potency of this type of toxin
Again, either you lie or you are an incompetent reader. Not really worth correcting this misstatement, since other readers know what I said and neither dishonesty nor poor reading comprehension are amenable to correction.

wikiRussian scientists who developed the nerve agents claim they are the deadliest ever made, with some variants possibly five to eight times more potent than VX,[8][9] and others up to ten times more potent than soman.[10] As well as Russia, Novichok agents have been known to be produced in Iran.[11]
No we are talking about the temperature of the metal, you claimed that anything above 700 degrees would only be found in a lab.
Deformation is a separate matter.
You asked. “What if Person A happens to be your own government?” Your question assumes that Person A is Person B’s government. According to your argument these are the same entity. Why would it need to sink a ship to send itself a message?
This would have been visible when the documentary guy filmed the hole last year, which implies he's incompetent or dishonest. This whole exercise seems to be a waste of time. The hole is a stress fracture caused by impact with the sea floor, not a bomb.
Sure, they will head back out next year and dive the wreck to gather more data but the sequence of events which sank the Estonia will not likely change.
Yes, it would be a staggering claim had I made it.Sorry, are you saying a nerve agent left in a public place didn't put people's lives at risk? That is a staggering claim.
Wiki
Sweden (Person A) is not Russia (Person B).
Sweden and Russia are totally independent of each other.
He's quoting YOU!
I never said I had A-Level Physics. Stop lying.
A quick google tells you: The hotness of the gas stove flame ranges from 600℃-3000℃ depending on two important factors. One of these important factors is the amount of energy beings released from fuel combustion, while the other important factor is the availability of pure oxygen rather than air to ensure complete combustion.
He deliberately juxtaposed Russia with the word Sweden in his first query, so he is less than honest.
Your question introduced a scenario in which Person A was Person B’s own government. Sweden is not Russia’s government.
"It depends". "Depending on". Without using the term 'depends' are you claiming a mig welding kit will achieve the same deformation on metal as a detonation? Are you saying the three laboratories Brian Braidwood sent his samples to were all lying when they said the deformation noted were indicative of a possible detonation of some force?
Sorry, are you saying a nerve agent left in a public place didn't put people's lives at risk? That is a staggering claim.
Wiki
Actually, what the Clausthal-Zellerfeld laboratory said was that 'as it [the sample provided by Braidwood] had not been treated in a laboratory to a temperature of 700 - 720 then...'.
In other words, it assumed no prior high heat treatment that would have caused the twinning deformation that was seen. It was stating its assumptions, which is quite conventional, that is all.
It's a translation from the German, which can trip up English speakers in respect of sentence structure. It is from this web page here.
No, he didn't. His query is shown below and is crystal clear:
How big do you think the welding kit that ship builders use is?
How big do you think the plasma cutters and gas torches they use to cut the plates and components are?
Deformation of the parts was caused by their failure due to stress, not due to heat.
We are talking about welding because you claimed that the only way the sample could have been heated is because of a 'detonation'.
