Examples
- The in situ prepared mno2 made for the production of la1 - xsrxmno3 phase , and avoided the semi - finished phase
450 950左右，主相生成950以上，整个体系反应基本结束。 - The impact toughness could be prominently improved by ag mainly because of the depressing of grain growth during the sintering , and some granuliform nd - rich phase appeared
Ag元素提高磁体冲击韧性主要是因为细化了主相晶粒并使颗粒状富nd相增多。 - Tempering can cause the boundary of main phase more straight and regular , and the quantity of micro - particles in the grain boundary will increase and these particles nail the neighbor boundaries . the co - effect of these factors improved the cocercivity of magnets
时效使主相晶界平直规整，从而使反磁化畴难以形核；同时，晶界中的微粒相数量增多，这些微粒相强化了对晶界相的钉扎作用。 - A dense protective scale , mainly a - al2o3 , formed on the surface of the samples , which could prevent samples from further oxidation . it was helpful to improve its high temperature oxidation resistance and shed new light on the application in high temperature circumstance
试样表面形成了一层主相为a一a12o3的致密保护性氧化膜，阻止了材料的内层发生进一步的氧化，从而极大地提高了材料的高温抗氧化性，为ti3sicz材料在高温条件下的应用提供新的研究思路。 - The microwave magnetic sintering can not only lower the sintering temperature and shorten the sintering time , but also decrease the micro - grain size of magnets and make intergranular phase and grain boundary of main phase distributed well . the abnormal grain growth was found in conventional sintered ndfeb magnets , which may be due to the greater particle size and uneven distribution of powder , and higher sintering temperature and longer sintering time . of course , the abnormal grain growth would deteriorate the magnetic properties
微波磁场烧结的不但降低烧结温度，缩短烧结时间，而且使磁体整体加热，受热更均匀，因而磁体晶粒更细小，并且主相晶粒边界趋于规则化，晶间相的分布更均匀；在常规烧结的磁体中则出现了晶粒异常长大现象，造成这一现象的原因，一方面可能是烧结温度过高或烧结时间过长，另一方面可能是磨制的粉体均匀性较差，存在的大颗粒被许多细小颗粒包围，在烧结过程中，大颗粒不断吞并小颗粒，逐渐长大，而异常长大的晶粒自然会导致磁体性能的恶化。
