Being certified as the top article by Center for Non-Destructive Evaluation (CNDE) on the conference on “Recent Advances in Railway Engineering (ICRARE 2021)”

The International Conference on Recent Advances in Railway Engineering (ICRARE) is one of the most prestigious and longstanding conferences in the field of railway engineering in West Asia. Up to date, six successful sessions of this scientific-industrial international event have been held by the School of Railway Engineering of Iran University of Science and Technology and have been very well received by many professors, researchers and local and foreign craftsmen. The 7th International Conference on Recent Advances in Railway Engineering (ICRARE 2021) was held on 18th and 19th of May 2021, with cooperation of all academic, research and industrial centers related to this field in the country. The Center for Non-Destructive Evaluation (CNDE) participated in this conference and presented a research paper entitled “Design and construction of a non-destructive system for detecting and measuring the amount of corrugation in the RDD-S11 rail defect detector device” and won the title of the best article.

Nondestructive detection of Microstructural Changes due to the Grinding Burn Using Electromagnetic Probes

Journal: Iranian Journal of Manufacturing Engineering

Publication date: 24 April 2021

Abstract:

Grinding burn is one of the most significant problems in grinding process with uncontrolled conditions and degrades the mechanical properties and performance of the part. The aim of the present study is to non-destructively evaluate the grinding burn phenomenon in steel parts. The parameters of the grinding process were changed to produce microstructural changes with different burn grades on the surface of steel parts. The results obtained from microscopic observations and micro-hardness tests revealed the occurrence of two types of burns including thermal softening (surface tempering) and re-hardening (formation of a hard white layer on the surface) burns.

Predicting hardness profile of steel specimens subjected to Jominy test using an artificial neural network and electromagnetic nondestructive techniques

Journal: Nondestructive Testing and Evaluation

Publication date: 04 Jun 2020

Abstract:

Based on relationships between electromagnetic properties and microstructural changes in steel, the current paper describes the development of an electromagnetic technique to determine steel hardenability, non-destructively. Performing Jominy end-quench test, magnetic hysteresis loop and eddy current methods have been applied to SAE 4140 standard steel samples to explore applicability of the non-destructive techniques for determining hardenability.
