Results of the experiments showed that the wear mechanisms of the sintered steel included abrasive wear, adhesive wear and fatigue wear, and it was the abrasive wear most important. it was the sintered steel mixed by ni, mo that was the best on the wear resistance, because of the great lot of bainite ; the sintered steel quenched and low temperature tempered mixed by mo, w that was the best on the wear resistance, because of the rigidity of the steel was the highest
實驗結果表明:本文中幾種燒結鋼的磨損機制均是由磨粒磨損、粘著磨損、和疲勞磨損共同作用的,且以磨粒磨損為主;在燒結態下,復合添加合金元素鎳、鉬的燒結鋼的耐磨性能最好,這是因為生成了大量的硬質相貝氏體;而淬火、低溫回火態下,則復合添加鉬、鎢的燒結鋼的耐磨性能最好,這是因為熱處理態下添加鉬、鎢的燒結鋼的硬度最高。Annealing could reduce hardness and raise toughness, which could be prone to mechanical machining. quenching and low temperature tempering could raise intensity and hardness of materials, not reduce toughness obviously. quenching on same temperature caused ticp / fe in situ composites having the best integral machine properties
退火處理使材料的硬度降低,韌性提高,便於機械加工;淬火+低溫回火處理使材料的強度和硬度提高,而韌性無明顯的降低;採用等溫淬火工藝,可使tic _ p fe復合材料具有最好的綜合機械性能。The results show that, with the quenching temperature ( 270 ~ 380 ) increasing, the carbon content and percentage content of retained austenite increase first and then decrease, which are up to a maximum value at 360 ; the tensile strength of adi decreases ; the elongation and impact ductility of adi increase first and then decrease, which are up to a maximum value at 360 ; but the hardness of adi decreases first and then increases, which is up to a minimum value at 360
結果表明,在試驗溫度范圍內( 270 ~ 380 ) ,試樣中殘余奧氏體的含碳量及其含量隨著等溫淬火溫度的升高先增大后減小,均在360等溫淬火時出現最大值;抗拉強度隨著等溫淬火溫度的升高而逐漸降低;伸長率和沖擊韌度隨著等溫淬火溫度的升高先增大后減小,在360等溫淬火時出現最大值;硬度則隨著等溫淬火溫度的升高先減小后增大,當360溫淬火時硬度最低。
