Investment Castings of Precipitation Kuomesa Stainless Simbi

Chinangwa chikuru chekugadzirisa kwakasimba kwekugadzirisa simbi isina tsvina ndeyekunyungudutsa carbides kana zvimwe zvikamu zvakanaya mukugadzirisa kwakasimba kuwana supersaturated single-phase chimiro. Kukandwa kwe austenitic stainless simbi, austenitic manganese simbi uye kunaya kunoomesa simbi isina tsvina kunofanira kazhinji kuve yakasimba mhinduro yakagadziriswa.

Martensitic precipitation inoomesa simbi isina tsvina kazhinji ine kabhoni isingasviki 0.1%. Simbisa nekuwedzera kuomesa zvinhu (mhangura, aruminiyamu, titanium uye aluminium, nezvimwewo) kugadzira kushayikwa kwesimba. Izvo zvemukati zvechromium zvinowanzokwira kupfuura 17%, uye huwandu hwakakodzera hwenickel hunowedzerwa kuti uvandudze kuramba kwecorrosion.

Kunaya kwemvura kunoomesa simbi isina tsvina imhando yealloy simbi ine kabhoni yemukati isiri yakakwira kupfuura 0.03% kuve nechokwadi chekuomarara, kusimba kwekusaora, kusimba uye kushanda kweiyo martensite matrix, uye 12% chromium kuve nechokwadi chekuonda. Mukuwedzera, iyo alloy element cobalt inowedzerwa kuti iwedzere kuvandudza kupisa kwekupisa kwesimbi.

Semi-austenitic precipitation inoomesa simbi isina simbi, kureva, kunaya kwekuchinja kunoomesa simbi isina simbi, ine isingasviki 12% chromium. Iyo ine yakaderera kabhoni yemukati, uye aluminium seyayo huru yekunaya inoomesa chinhu. Kunaya kwemvura kunoomesa simbi isina simbi kune kuita kurinani pane kunaya kwemartensitic kunoomesa simbi isina simbi.

Austenitic precipitation inoomesa Stainless simbi isimbi isina simbi ine yakagadzika austenite chimiro munzvimbo dzakadzimwa nekuchembera. Iyo nickel yemukati uye manganese yemukati yakakwira, uye iyo chromium yemukati yakakwira kupfuura 13% kuti ive nechokwadi chekuramba kwecorrosion uye oxidation kuramba. Panguva imwecheteyo, austenitic precipitation inoomesa simbi isina tsvina inowanzowedzera titanium, aruminiyamu, vanadium kana phosphorus semvura inoomesa zvinhu, uye inowedzera hushoma hweboron, vanadium, nitrogen nezvimwe zvinhu kuti uwane zvakanakisa zvivakwa.
