The precipitate effect depends on difusion. If you constantly expose the material to a high temperature, the effect will be accumulated because more precipitates will form and eventually they will become incoherent. The behavior of the ageing should be very similar between these two alloys.
I'm sorry, a co-worker alerted me that I mistranslated it.
Those lines are called deformation twin bands in english.
It can be formed close to the weld due to thermal stresses. It's hard to say without further information if its due it because those can be formed during solidification or heat...
As I see the only way to correctly evaluate the fatigue behavior of a structure would be to do testing to either assess the fatigue endurance of such structure as close as the final form and material (and environment, surface condition and number of cycles) as possible or to apply fracture...
Well, if you think that the extinction of CAD drafters is the future, I'm a time traveler.
I worked to a company that didn't had (and due some news from former co-workers I believe it hasn't changed over the last year) a single CAD drafter. All the drafting and detailing work would be delegated...
Overqualified is a commom place when the employer (or the people responsable for the hiring process) doesn't feel you're suitable and don't want to be rude.
Not that I particularly agree with the aproach or think it is less rude than telling the real reason (wich I rather have than this generic...
RFreund,
It is not basic, bolts present complex mechanical behavior. If you use the theory o solid mechanics that would be correct, but in real world situations there would be plane strain conditions allied with plane stress conditions due to misalignment, yelding of the bolt and the vicinity...
Well, from my short work experience I will tell you that you can actually use your knowledge and scientific basis to solve a lot of day to day real world problems. The thing is that lots of people that I came across didn't do this and didn't apreciated it either when someone else tried to do...
Ron,
It should refer to welding hidrogen embrittlement, but in the fact it discuss the H influence on high content hydrogen environments on the bulk material.
It is funny how the article itself mention the plastic-like deformation yet discuss embrittlement - hydrogen on steels is deleterius...
If they paid a headhunter comission for finding someone who doesn't fit the corporation and will leave for a slitghtely higher wage (or actually a salary wich fits his position) then they might have to re-think their hiring process and this headhunter.
If something like this became a problem...
