晶粒大小分布 meaning in Chinese

crystallite size distribution

The analyses of their microstructure showed that comparing with zl101 that contained no titanium , the trace amounts of titanium in alloys caused grain refining of al - l % si in zl101a prepared from electrolytic low content titanium aluminum alloy ( i . e . alti101a ) and zl101a prepared from electrolytic al - si - ti alloy ( i . e . ast101a ) , and the grain size distribution became more even , whereas the trace amounts of titanium have little influence on the size and shape of si particles in these alloys
微观组织分析结果表明，相对于不含钛的zl101 ，微量的钛可以使电解低钛铝合金制备的zl101a ( alti101a )和电解铝硅钛合金制备的zl101a ( ast101a )的( al )相的晶粒细化，晶粒大小分布均匀，但对它们的si粒子尺寸和形貌影响不大。
We apply the system to the ultra - fine grain steel welding , the simulated mean grain size in cghaz agreed well with the corresponding independent experimental data . in this paper , three factors influencing the grain growth , the steep temperature gradient in haz . the grain boundary liquid and the precipitates particle , were studied specially using mc technique
研究表明温度梯度造成的“热钉扎”现象和晶界液化现象都对靠近熔合线附近的晶粒长大有明显的阻碍作用，对最终的晶粒大小分布有重要的影响：而800mpa超细晶粒钥中的tin粒子山于溶解温度高，抑制奥氏体晶粒长大的效果十分显著。
