GB Qib DH 690 GB 712 Mechanical Properties
Cov khoom siv tseem ceeb yog elasticity, plasticity, nruj, aging rhiab heev, lub zog, hardness, cuam tshuam toughness, qaug zog thiab tawg toughness.
Elasticity:Cov khoom siv hlau deforms thaum nws raug rau sab nraud quab yuam. Thaum lub zog sab nraud raug tshem tawm, nws tuaj yeem rov qab tau nws qhov qub.
Plasticity:Lub peev xwm ntawm GB Qib DH 690 GB 712 los tsim cov deformation mus tas li yam tsis muaj kev puas tsuaj rau sab nraud.
Kev nruj:Lub peev xwm ntawm GB Qib DH 690 GB 712 los tiv thaiv elastic deformation nyob rau hauv kev ntxhov siab.
Lub zog:Lub peev xwm ntawm GB Qib DH 690 GB 712 los tiv thaiv deformation thiab tawg nyob rau hauv sab nraud rog.
Hardness:Lub peev xwm ntawm GB Qib DH 690 GB 712 los tiv thaiv lub siab ntawm cov khoom nyuaj rau hauv nws.
Impact toughness:Lub peev xwm ntawm GB Qib DH 690 GB 712 los tiv thaiv kev puas tsuaj hauv kev cuam tshuam kev thauj khoom.
Fatigue zog:Qhov siab tshaj plaws kev ntxhov siab uas tsis ua rau pob txha tawg thaum GB Qib DH 690 GB 712 raug rau ntau dua lossis hloov pauv.
Fracture toughness:ib qho kev ntsuas kev ua tau zoo siv los cuam tshuam GB Qib DH 690 GB 712 muaj peev xwm tiv thaiv kev tawg tsis ruaj khov thiab nthuav dav
