Medium Mn lightweight steels with a relatively higher content of 9–12 wt% have been actively developed recently to meet the demands crashworthiness and vehicles. In this study, combined intensive quenching (IQ) deep cryogenic treatment (DCT) was first proposed achieve microstructural homogeneity as well final strength–ductility synergy medium segregation bands, together comparison conventional ...

The design, fabrication, testing and analysis of a microchannel heat exchanger, a key component for a microminiature Joule-Thomson Cryogenic Refrigerator is described. Results show that the heat exchanger can be fabricated efficiently and economically with the existing manufacturing technology. The heat exchanger was tested to be mechanically robust and durable under high pressure operating con...

Solid malignant tumors are one of the leading causes of death worldwide. Many times complete removal is not possible and alternative methods such as focused hyperthermia are used. Precise control of the hyperthermia process is imperative for the successful application of such treatment. To that end, this research presents a fast method that enables the estimation of deep tissue heat distributio...
