    By Julian Speck at TWI Ltd., and Afshin Motarjemi at TWI

    TWI's Members recently requested an evaluation of the instrumented indentation technique (IIT). IIT is claimed to be capable of determining tensile properties from a local indentation similar to a hardness test. TWI subsequently investigated the capability, usefulness and limitations of the IIT and some of the findings are reported here. IIT is sometimes known as ABI (automated ball indenter) testing. There are many manufacturers' o fIIT or ABI units that provide equipment and/or testing services. Two leading manufacturers of IIT equipment are Advanced Technology Corporation in the USA, and Frontics in Korea. In this investigation, FRONTICS kindly offered to collaborate with TWI on the project.
