Compressive behaviour of titanium iron alloys: data

Full description

This dataset is part of a collaboration cluster project, between the Centre of Excellence for Design in Light Metals and the CSIRO which was funded by a CSIRO Flagship Cluster grant from 2006-2009. The project examines the mechanical properties of titanium iron alloys. Compression tests are carried out in order to observe the behaviour of the alloys at different temperatures and different speeds. The raw data consists of stress versus strain measurements relating to 3 alloys, 3 compositions, 3 temperatures and 3 strain rates. Colleen Bettles from Monash University worked with Sreekumar Vadakke Madam from Deakin University to obtain the raw data in a csv file using Instron for compression. Stress and strain are measured throughout the test with a different series of tests for each subtle change in the composition of the alloy. The basic stress strain curve is calculated from the raw data and further information is generated from subsets of the data. For example, for a single temperature, what is the effect of strain rate? And for a single strain rate, what is the effect of temperature? Using pro Fit (OS Mac), it is then possible to combine 2 results together to produce a processing map. The map calculates an efficiency, which is a measure of where it is easiest to process the alloy. Thus a processing map for the base alloy calculates an efficiency of using a high temperature and a low strain rate. By varying the composition of the alloy, the goal is to find areas where faster strain rates and lower temperatures of processing can used which require less energy. The processing maps act as a visual aid. There is also a document detailing the measurements made in each test.

Notes

27 x csv files (one file for each alloy at each temperature and each strain rate); Pro Fit files (processing maps).

Significance statement

The data containing stress versus strain measurements makes it possible for the composition to be reproduced. A processing map allows a researcher to find areas where faster strain rates and lower temperatures of processing can used which require less energy.
