Abstract
The yield strength, tensile strength, and hardness of Type IV dental casting gold alloys were measured. Regression lines and prediction intervals for the estimation of yield strength and tensile strength from hardness measurements were then determined. The 95% prediction intervals for the yield strength and tensile strength were found to be +/- 45 MN/m2 and +/- 105 MN/m2, respectively.
摘要
对IV型牙科铸造金合金的屈服强度、抗拉强度和硬度进行了测量。然后确定了根据硬度测量值估算屈服强度和抗拉强度的回归线及预测区间。发现屈服强度和抗拉强度的95%预测区间分别为±45 MN/m²和±105 MN/m²。
