Dadi carane sampeyan nyegah produksi quenching kaku sakbasis cetakan presisi standaradhem?
A tempering kudu digunakake kanggo ngilangke kaku, lan sawise quenching model standar, godhok 30 ~ 60min sadurunge cooling perawatan, mbusak 15% kanggo 25% quenching kaku, stabil aus ampas, banjur digawa metu - 60 ° C perawatan cooling conventional utawa jero kadhemen. perawatan saka -120 ° C.

Suhu sing luwih murah, luwih akeh transisi austenite residual minangka jumlah martensit, nanging ora bisa diowahi. Asil eksperimen nuduhake yen sisa austenite kira-kira 2% nganti 5%, lan jumlah austenit sing sithik bisa nggawe stres lan buffer alon. Wiwit austenite ampas iku alus lan angel, bisa sebagian nyerep energi saka expansion cepet bisa, ngilangke phase owah-owahan kaku. Sawise perawatan kadhemen, model standar dijupuk metu ing banyu panas kanggo panas suhu, lan 40% -60% kaku perawatan kadhemen bisa ngilangi. Nalika suhu mundhak menyang suhu kamar, kudu tempered ing wektu kanggo luwih ngilangke kadhemen perawatan kadhemen, supaya mbentuk retak perawatan kadhemen, entuk tissue stabil lan kinerja, mesthekake yenbasis cetakan presisi standar ora deformable sajrone panyimpenan lan panggunaan.
