中文摘要 | 本研究乃是採用兩種不同成分的410不鏽鋼銲帶,以潛弧銲法實施堆積 銲(Bead on Plate),以探其冶金特性及銲後熱處理溫度對硬面銲補層耐磨耗特性之 影響。實驗中對兩種銲材施以 625°C、650°C、675°C之銲後回火處理後,分 別進行耐磨耗實驗,並對直銲下、回火下等試片量測硬度,觀察其光學、SEM、 TEM等顯微組織,分析其碳化物結構,以瞭解材料成份及銲後熱處理溫度與顯 微組織、耐磨耗性之關係。經過實驗分析,綜合規納以下結論:一、410麻田散鐵 不鏽鋼之碳化物為面心立方(FCC)結構的(Fe,Cr)�yC�葦活A添加Mo元素後,其碳 化物為斜複雜面心結構(Fe,Cr,Mo)�yC�葦活C二、添加Mo會析出Mo碳化物,其 析出溫度較低,成顆粒狀,量多且細,對耐磨耗性有正面影響 。三、添加Ni 會降低材料之AC�腋傴A溫度,增加回火軟化效果,並沿晶界析出長條狀之碳化 物,造成晶界弱化,對耐磨耗性有不利之影響。四、銲道硬度隨回火溫度提高而 降低。五、碳化物析出量隨回火溫度提高而增加。六、材料耐磨耗性不以硬度為 指標,碳化物的析出為主因,以量多、質硬、體細、成顆粒狀較優。七、銲帶式 銲補之熔填率高,稀釋率低,銲後加工量少,對提高硬面銲補之工作效率及銲接 品質助益甚大。 |
英文摘要 | The effect of postheat treatment on wear resistance of SUS 410martensite stainless steel hard-facing weldment is stud-ied . Thematerials examined in this study had a base cr type SUS410 @'artens@t@cstainless steel strip with two different compostions . The str-ips were" bead on plate " weld by Sumerged-Arc welding process and thenevaluated the effects of metallurgical properties and postheat-treating temperatures on wear of the weld pools . In th-is study ,specimens were annealed at 625 , 650 and 675°C after welding. Theheat-treated specimens were then characterizec Its nncrostructuresusing opt-ical metal lgraph, SEM , TEM , wear resistivity and hardnesstests. Such experiments can provide fundamental infornmation about theinfluence on wear resistivity of the microstrueture . composition andpostheat-treating temperature.Specific conclusions are as follows:1. The carbide of SUS 410 martensitic stainless steel is FCC Cr�yC�群tructure, By adding Mo element , the carbide was found to be(Fe,Cr,Mo)�yC�� structure.2. By adding Mo element , the prepcipitation of Mo carbide is more amount and fine, resulting in higher wear resistivity.3. By adding Ni elenent, the AC�� temperatuires of the material tended to be decrease , that are associated with temper-softening subsequent to be grain boundary carbides are developed along the grain boundaries , in the form of long , needle-like .laths . |
