[The effect of cryotreat on the mechanical properties of the medium and high melting-point castable alloys].
Two mechanical properties that are closely related to the clinical practice, i.e. the surrendering toughness and the hardness, of the medium and high melting-point castable alloys, were tested before and after the cryotreat. The results showed: 1. Cryotreat significantly increased the surrendering toughness of the medium and high melting-point castable alloys (40.00%); 2. Cryotreat significantly increased the surrendering toughness of the medium and high melting-point castable alloys (25.45%); 3. Cryotreat significantly increased the surrendering modulus of the high melting-point castable alloys (25.77%); 4. Cryotreat significantly increased the hardness of the medium melting-point alloys(24.40%); 5. Cryotreat significantly increased the hardness of the medium melting-point alloys (7.77%). These results suggest that cryotreat is an effective procedure in enhancing the toughness and hardness of the medium and high melting-point castable alloys.
