hardness test [机] 硬度试验
- The effect of uncertainty evaluation in Rockwell hardness test is described by analyzing and calculating the uncertainty of metal in Rockwell hardness With a rolling deformation of90%, the recrystallization temperatures( T_ R) of tantalum plates whose ingots were made by powder metallurgy( PM) and electron beam melting( EBM) were determined by micro hardness In addition, another experiment was carried out that the powdered aluminum and copper was pressed in one die with a same pressure and infiltrated them after that with a hardness test of the alumini
本文还试验了通过铜粉与铝粉在同一模具内,同一压力下压制后熔渗的实验,并对渗后的试样进行了硬度测试和微观组织的观察。
