Cov khoom ntawm TC4 vs Commercially Ntshiab Titanium

TC4 titanium muaj zog ntau dua li cov khoom lag luam ntshiab titanium qib, tab sis me ntsis txo ductility thiab toughness. Nov yog qhov sib piv ntawm qee qhov ntawm lawv cov khoom tseem ceeb:

0.2% Tawm Zog - TC4: 880 - 970 MPa vs CP Ti: 170 - 480 MPa

Tensile zog - TC4: 930 - 1020 MPa vs CP Ti: 240 - 550 MPa

Elongation ntawm Break - TC4: 10% - 18% vs CP Ti: 20% - 35%

Qhov ceev - TC4: 4.43 g / cm3 vs CP Ti: 4.5 g / cm3

Elastic Modulus - TC4: 115 GPa vs CP Ti: 105 GPa

Fatigue Strength - TC4: 400 - 500 MPa vs CP Ti: 200 - 300 MPa

Fracture Toughness - TC4: 75 MPa-m^0.5 vs CP Ti: 55 - 115 MPa-m^0.5

Corrosion Resistance - Ob leeg muaj kev tiv thaiv zoo heev vim yog cov txheej txheem oxide passive.
