An Ultrasonic Force Microscope capable of imaging elastic modulus variations with nanometer resolution has been developed by modifying a Scanning Probe Microscope. Images of ultrasonic properties have been simultaneously obtained with the topography images. The technique has been utilized to characterize nanoscale copper droplets and grains deposited on a quartz substrate by ionized cluster beam deposition. Images of the same region obtained with atomic force microscope, lateral force microscope, and ultrasonic force microscope are compared. The origin of image contrast in ultrasonic force microscopy and its utilization for quantitative elastic property measurement of nanometer particles are discussed.

One of the goals of the DOE PNGV, DOE Freedom Car and Vehicle Technologies, Freedom Car and Fuel Program, United States Automotive material Partnership (USAMP) is to reduce vehicle weight by 50 % by using lightweight materials in place of current steels. The project objective is to develop high performance, low-cost, lightweight aluminum metal matrix composite components for use in automotive drive train applications. The targeted application is to produce net-shape gears using Dynamic Magnetic Compaction.
