Research into interrelations between plasticity and hardness of standardstrength steel grades Исследование взаимосвязей пластичности и твердости сталей стандартных категорий прочности
The objective of the study is research into interrelation between values of plasticity(d, y) and hardness (HB).Numerical values of hardness are insufficient to make accurate assessments of plasticity values. Meanwhile, hardness is the property identified using small-sized samples extracted from the metalwork of restored and reconstructed buildings. The most suitable method is the Rockwell one used to obtain HRB or HRC hardness values. However, these values maintain an analytical relationship neither with durability, nor with plasticity values. The difference between metal testing methods consists in their relation to dimensions: HRB and HRC values are dimensionless, while HB values are size dependent (kgf/mm2, or MPa). Therefore, the approach employed in this article can be used to generate supplementary information about the properties of metals using HRB or HRC hardness measurements.It is noteworthy that the proposed technique of coordination of HRB hardness val-ues with HB hardness values may be employed to, first, analyze σ and σ sizes using HBт вvalues, and second, to identify the nature of relationship between HRB, on the one hand,and d and y values, on the other hand, to compose the equation of relative strength and plasticity values and to assess the most important factor of reliability of metals.
До настоящего времени считается, что по числовым значениям твердости не удается достоверно оценить показатели пластичности. Между тем именно твердость является доступным свойством, определяемым на малогабаритных образцах, вырезанных из металлоконструкций реставрируемых и реконструируемых зданий. В большей степени для этого подходит метод Роквелла, позволяющий получить экспериментально числа твердости HRB или HRC.
