Correlation of the hot-hardness with the tensile strength of 304 stainless steel to temperatures of 1200°C

On the Prediction of Strength from Hardness for Copper Alloys

“…Such relations can be useful in the design, where direct measurement of tensile properties is not viable. These relations are always attractive as they bring down the number of tests to be conducted to ensure the quality of the materials [4,5]. As these methods are fast and relatively non-destructive in nature they are effectively used in failure analysis [5,6].…”

“…All the expressions mentioned previously require the knowledge of strain-hardening coefficient, which can be directly determined from uniaxial tensile or compression test and indirectly through Meyers hardness measurement and empirical relations [4]. Apart from these, few methods were proposed for estimation of strength for metals using an indentation technique in the literature [4][5][6][7][8][9].…”

“…Most of the correlations available were obtained by analysis of data for steels [1][2][3][4][5][6][7][8][9][10]. Therefore, an attempt has been made to propose correlations to estimate the strength from hardness for copper alloys.…”

Effects of minor alloying additions on the strength and swelling behavior of an austenitic stainless steel

“…A correlation does exist between hot hardness and ultimate strength (4). Since the hot hardness technique involves simple specimen preparation and easily made measurements, it can be used to screen rapidly a large alloy set.…”
