The new URQ HIP cooling systems give the opportunity to investigate the impact of pressures up to 2000 bar on phase transformation time dependency. For each of the two materials in this study, a comparison of austenite phase transformation time at 100 bar and 1700 bar was performed. The study was performed by isothermal heat treatment of specimens for a specific time followed by quenching. To evaluate the influence of pressure on hardenability, the phase fractions were evaluated using grid method on SEM images. The study found significant influence of HIP pressure on hardenability.
Material densification is a critical process for many manufacturing and materials processing applications. By using high-pressure techniques, materials such as metals, ceramics, and composites can be compressed to higher densities, resulting in increased mechanical properties and performance.
Quintus Technologies’ High Pressure Processing (HPP) is a natural, scientifically validated technology for food processing. HPP delivers food safety benefits, extends shelf-life, and maintains flavor, freshness, and nutrients. HPP uses ultra-high pressures instead of high temperatures and preservatives to inactivate foodborne pathogens, reduce waste, and deliver natural and nutritious.
