Impact strength of toughened alloys varies greatly with temperature
Sorun Belirtisi
Toughness is good at room temperature but embrittles rapidly at low temperatures
Neden Analizi
The Tg of the toughening phase (rubber) is higher than the test temperature and loses elasticity; the matrix embrittles at low temperature; interface bonding force decreases at low temperature
Çözüm
Select toughening rubbers with lower Tg (such as EPDM, POE); increase the toughening phase dosage; optimize interface compatibilization
Temel Çıkarım
The temperature resistance range of toughened alloys is strictly limited by the Tg of the toughening phase
