  1. The grain refining process for 18ni 2450mpa martensite aged steel

    馬氏體時效鋼細化晶粒工藝
  2. 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

    研究表明，採用本文提出的摩擦壓扭強變形區轉移法可以得到棒狀的超細晶材料，軸向壓力、扭轉速度和溫度是採用該方法制備超細晶材料的主控參數；試件的旋轉轉速和冷卻速度對變形區晶粒細化和硬化效果影響顯著；超細晶ly12的壓縮性能與淬火+自然時效狀態的ly12壓縮性能相比，斷裂強度和延伸率均有一定程度的增強；超細晶ly12的熱膨脹系數在550左右發生明顯的變化。
  3. 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

    金屬強化的幾種主要方式：細晶強化，位錯強化，晶界與亞結構強化，第二相強化，固溶強化，細晶強化以及trip強化等都在等溫淬火球鐵中得到了體現。
  4. Grain - refining aluminium ingots

    結晶鋁錠
  5. 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

    微觀組織分析結果表明，相對于不含鈦的zl101 ，微量的鈦可以使電解低鈦鋁合金制備的zl101a （ alti101a ）和電解鋁硅鈦合金制備的zl101a （ ast101a ）的（ al ）相的晶粒細化，晶粒大小分佈均勻，但對它們的si粒子尺寸和形貌影響不大。
  6. Effect of deforming method on grain - refining in 20mn2 steel containing zrc particles

    2鋼晶粒細化的影響
  7. 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

    結果表明， ti對晶粒的細化可以大幅提高試驗合金的抗拉強度、延伸率和斷裂韌性，但對合金的屈服強度影響不大。
