Evaluation of mechanical properties of ductile cast iron and inverse regression
Machines. Technologies. Materials., Vol. 13 (2019), Issue 4, pg(s) 183-186
The evaluation of ductile cast iron is common foundry practice. For the correct non-destructive evaluation (NDE) of mechanical properties (ultimate tensile strength; relative lengthening; Brinell’s hardness; elasticity modulus) by means ultrasonic testing and inverse regression analysis are used.
