hey all.
i am making a sample of bulk tungsten.
but i am getting only about 84% denstiy...
can anyone suggest a mathod of improving it?
i do not want to change my sintering process so the method should be after i get the bulk...
so... anyone can suggest a process to go from 84% bulk...
hey all.
i was wondering what's the diffrance between quasicrystal diffraction pattern and normal crystals (single and multiple)..
where can i find some info about the diffrences?
thanks ,
alon
well...i was afraid the answer would be the arc...
but how did the guy in 1940 made his diagram? i now he made it in some sort of experiment...but i don't know how...
thx for the answer, but still...
i was kinda hoping for more information about the first diagram that was made...in 1940...
i was hoping to find the way HE did it...
the final purpose is to succesfully make a bulk from tungsten-aluminium that can holg great temp...
but i am having...
hey all.
i am doing some research about the Al-W system.
and i wanted to find out how the diagram was made.
i searched and found who made it -
Clark W.D.: "THE ALUMINIUM-TUNGSTEN EQUILIBRIUM DIAGRAM", J. Inst. Met. 66 (1940)
271–286.
but i can't find any more info , and i cand...
hellp all..
i was doing a lab today and we use C6H3Cl3.
and i was told that it is dangerous and it can cause cancer.
why is that? what makes it so dangerous?
thanks.
hello everyone.
a little question...(or mybe two...)...
why does vickers and brinell hardness test have the units of stress ?
and why does rockwell test has no units at all ?
thanks to all !
