उदाहरण वाक्य

1. The grain refining process for 18ni 2450mpa martensite aged steel
2. The results indicated that more perfect alloy powders was obtained by attritor mechanical milling with upper efficiency . nd2fe14b grain refined quickly with increasing milling time and disappeared
3. The results showed that the grain refining by the trace amounts of titanium could improve the tensile stress , percentage elongation and fracture toughness , but had little influence on their yield stress
4. All main ways of metal strengthening including grain refining strengthening , dislocation strengthening , grain boundary and substructure strengthening , second phase strengthening , solid solution strengthening , as well as trip strengthening and so on , have totally found expression in the adi
5. The results indicated that , the fabrication process of ultra - fine grain material is mainly determined by the stress , rotate speed and the flux of cooling water . the grain refining and the hardening effect are mostly affected by the rotate speed and the flux of cooling water . compared with commercial ly12 , the invalidate strength and the prolongation rate of the ultra - fine grain material are properly improved in the measurement of compression property ; and the abrupt change of the dilatability of the ultra - fine grain material at 500c is found ; also the phenomena of which the grain size of these microstructures is stable when annealed under 300c is observed
6. 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
