Rombouts, Huub (author)Liquid metal embrittlement (LME) is a problem encountered in the resistance spot welding joining process of advanced high-strength steels in the automotive industry. Its occurrence reduces the mechanical performance of welds. The nature of resistance spot welding prevents in-situ characterisation of thermo-mechanical conditions causing LME....master thesis 2021

Eftekharimilani, P. (author)The potential for weight reduction, ease of manufacturing and improved crashworthiness makes advanced and ultra high strength steels attractive for automotive applications. Resistance spot welding is by far the most widely used joining method in the automotive industry due to the high operating speeds, the reliability of the process and the...doctoral thesis 2019

Eftekharimilani, P. (author), van der Aa, EM (author), Hermans, M.J.M. (author), Richardson, I.M. (author)This paper presents the effects of double pulse resistance spot welding (RSW) on the microstructural evolution, elemental distribution and mechanical properties of a 3rd generation 1 GPa advanced high strength steel (AHSS). In order to investigate the effect of double pulsing, the steel was exposed to single and various double pulse RSW...journal article 2017

Den Uijl, N.J. (author)The introduction of advanced high strengths steels enabled automotive manufacturers to simultaneously reduce weight and increase safety of vehicles. However issues were reported concerning the weldability of these steels. These issues concerned both the manufacturability as well as the performance of resistance spot welded joints. The...doctoral thesis 2015

Amirthalingam, M. (author), Van der Aa, E.M. (author), Kwakernaak, C. (author), Hermans, M.J.M. (author), Richardson, I.M. (author)The partitioning behaviour of carbon, phosphorous and boron during the solidification of a resistance spot weld pool was studied using experimental simulations and a phase field model. Steels with varying carbon, phosphorous and boron contents were designed and subjected to a range of resistant spot welding thermal cycles. Mechanical properties...journal article 2015
