Dr. Jarrar's research is mainly concerned with the advancement of the Superplastic Forming (SPF) process. This is a manufacturing process used to form certain types of highly ductile materials into complex useful components.  The process consists of heating a superplastic material sheet placed on a single-piece die to the required superplastic forming temperature of that material. Controlled pressurized gas is then applied on the upper part of the sheet, forcing the sheet to take the internal shape of the die.  With the current high demand for fuel efficient cars there is an increasing interest towards making SPF, the manufacturing choice for lightweight body panels in the automotive industry.
