| Abstract Scope |
Controlling the microstructure of components is of interest to achieve optimal final part properties, i.e., materials by design. The manufacturing process itself can affect a material’s characteristics by changing the microstructure. For example, past research has shown that an austenite to martensite phase transformation in stainless steel occurs during deformation. Temperature is known to have a significant influence on this phenomenon. In this paper, the effect of temperature on the austenitic to martensite phase transformation in SS 316L under uniaxial tension is investigated. Both a cooling system and a heat exchanger were employed in a uniaxial tension experimental setup to control the temperature. Tensile specimens were strained to fracture at four temperatures of -15°C, 0°C, 10°C, and 20°C. Digital imaging correlation (DIC) and a thermal imaging camera were used for tests at 0°C and above to capture strain and temperature data, respectively. Strain data could not be obtained at -15°C due to the DIC paint flaking during testing. X-ray diffraction was used to measure the weight percent of martensite in both the as-received and the tensile-tested materials. |
