中文拼音 [cuìtòudù]
淬透度
英文
hardenability-
Abstract : the structure and the properties of the grinding ball made of the composite cast iron have been researched in this paper. the result indicates that added trace boron and a proper quantity copper to this kind of composite cast iron can increase its quench - hardening ability, and raise its hardness and impact toughness
文摘:研究了一種復合鑄鐵磨球的組織和性能，結果表明，化學成分和淬火工藝對這種復合鑄鐵磨球的組織和性能有很大影響，微量的硼和適量的銅可以明顯地提高磨球的淬透性，經過余熱淬火得到貝氏體或馬氏體基體組織，從而提高磨球的硬度和沖擊韌性。Near b - titanium ti - 1023 alloy of high - strength, good fatigue strength and excellent hardenability has both a relatively low 3 - transus temperature ( 798c ) and a low forging temperature range, which make it suitable for superplastic isothermal forging to manufacture complex forge pieces
Ti - 1023合金屬于近型鈦合金，具有高強、高韌、高淬透性等特點，而且它的相變溫度（ 800左右）和鍛造溫度均較低，非常適合於採用超塑性等溫模鍛方法製造復雜鍛件。First of all, every heat treated sample were analyzed by using optical microscope ( om ). sequently x radio diffraction ( xrd ) was used to study the original sample. we also studied the microhardness of the sample which were quenched in water and aged at different temperature. further more, the original sample was analyzed by using transmission electricity microscope ( tem )
首先，對各熱處理態試樣進行了金相（ om ）分析，並對原始樣進行了x射線衍射（ xrd ）分析，接著測試了水淬試樣在不同時效時間的顯微硬度，還制備了原始樣的電鏡試樣，並用透射電鏡（ tem ）進行了觀察和分析。
