Kodi pulasitiki yotentha ndi chiyani ndipo ndi pulasitiki?

Pulasitiki wotentha ndi mtundu wa alloy pulasitiki womwe umayamba kuchokera ku mapangidwe a mamolekyu a polima ndikuphatikiza ukadaulo wosinthira polima kuti apange gawo laling'ono laling'ono, kuti akwaniritse kusintha kwadzidzidzi kwa ma macroscopic.
Pulasitiki wotenthedwa ndi mtundu wazinthu zomwe zimawonetsa kulimba ndi kulimba kwa pulasitiki ikagwidwa ndi mphamvu yokhazikika kapena yotsika kwambiri, ndipo imawonetsa zinthu ngati mphira komanso zotengera mphamvu zikamakhudzidwa ndi mphamvu yothamanga kwambiri, ndipo sizimakonda kulephera brittle.

Ili ndi mphamvu komanso kulimba kwa mapulasitiki aukadaulo wamba ikakhala yosasunthika kapena kutengera mphamvu yotsika kwambiri, ndipo imakhala ndi mawonekedwe a ductility ngati mphira komanso kulimba pamene ikukhudzidwa ndi mphamvu yothamanga kwambiri, kuti itenge mphamvu ndikuteteza. .zotsatira.
Poyerekeza ndi pulasitiki wamba toughened, pamene mapulasitiki wamba toughened kukhudzidwa ndi kuthamanga kwambiri, kuchuluka kwa kuyambitsa ming'alu ndi zochitika zowonjezera zidzachitika, pamene mapulasitiki olimba amangosonyeza kulimba ngakhale pamene zinthuzo zawonongeka ndi mphamvu yakunja.Kuwonongeka kopanda kulephera kwamphamvu monga ngodya zakuthwa ndi ma splinters.
Mapulasitiki otenthedwa nthawi zambiri amagwiritsidwa ntchito pokongoletsa mkati ndi kunja kwa magalimoto, zida zamasewera, zida zoteteza masewera ndi magawo ena.
