CTOME is a FORTRAN software dedicated to the processing of data in metallurgy. The software is being developed in the frame of research conducted in the Materials Engineering Department at the University of British Columbia. CTOME is developed to be a powerful software for the metallurgical scientist that requires a fast access and treatment to large amount of data.

MODULES

CTOME is composed of several independent modules. Each module is dedicated to a different group of processing tasks. The modules are often complementary to each other, e.g. the results of one module can be the input of another module. The modules do not share variables, making them simultaneously available. The software can run with all modules installed or with a selection of modules.

The modules available are:

• PROFILE, Processing of datafile
  

Processing of multiple files having a similar structure. Functions available: navigation, smooth, windows average, interpolate, derivate, integrate, normalize, column operations.

• LUMFILE, Analysis of LUMet file
  

Analysis of binary Laser Ultrasonic Files for the evaluation of the ultrasonic delay and attenuation spectrum. Couple the Gleeble files and ultrasonic delay and attenuation spectrum for the evaluation of metallurgical parameters such as grain size, fraction transformed and recrystallized fraction.

• STAFILE, Statistical Analysis
  

Group a set of statistics function for the analysis of grain size obtained from metallography in order to assist the comparison with laser ultrasonics grain size.

• WAVFILE, Waveform spectrum Analysis

Analysis of the frequency content of an individual time-amplitude waveform for the measurement of delay, attenuation spectrum and the related metallurgical parameters, e.g. FEM simulated waveform.

• TEXFILE, Ultrasonics Texture Analysis

Group a set of functions for the study of ultrasound propagation in textured materials, dedicated to the evaluation of ultrasonics parameters from the texture information measured ex-situ.

 

FEATURES

The CTOME software contains the following features:

• Local minimum localization
• Waveform synchronization
• Waveform windowing
• Fourier Transform analysis
• Advanced averaging
• Cross correlation function evaluation
• Amplitude spectrum calculation
• Attenuation spectrum analysis
• Normalization function
• Noise estimation function

Currently, the metallurgical parameters that can be evaluate in real time during a thermo mechanical treatment are the following:

• Mean grain size of material from the ultrasound attenuation
• Fraction transformed from ultrasound velocity
• Recrystallized fraction from ultrasound velocity
• Elastic modulus from ultrasound velocity
• True and Engineering stress flow curve from mechanical testing
• Fraction transformed from dilatometry
• Start and end transformation temperature
• Coefficient of linear expansion
• Heating and cooling rates
