For sintering of green powder compacts of copper, choose the correct statement: P. Sintering should be done in an inert or reducing atmosphere. Q. At a given sintering temperature, the rate of shrinkage will be higher for finer powder size. R. Full density parts can be produced in a finite time by solid state sintering S. Sintered compacts will have a higher strength than those made by metal working In which of the following reactions, application of vaccum will help? Liquid steel contains initially 0.05 mass% P and this has to be reduced to 0.01 mass% using a basic slag. The equilibrium distribution ratio of P between slag and metal is $$Lp = \frac{{\left( {\% P} \right){\text{slag}}}}{{\left( {\% P} \right){\text{metal}}}}, = 80;$$ Assuming that in itially the slag does not contain any phosphorous (P), then the minimum weight of slag (ton) required per ton of steel is What is role of matrix in composite Which penetrant process is best suited to detect shallow discontinuities?
