Influence of Mechanical Parameters on Corrosion Behavior of Metal Coupons in Simulated Environmental Conditions
Abstract: This study investigates the influence of mechanical parameters—namely applied stress, surface roughness, and deformation history—on the corrosion behavior of metal coupons exposed to corrosive environments. Mild steel and aluminum alloy specimens were prepared with controlled variations in tensile stress, polishing grades, and cold-working levels to simulate real-world mechanical influences. These coupons were immersed in a 3.5% NaCl solution under ambient conditions, and their corrosion rates were monitored over a 30-day …

Corrosion Measurement and Hardness Test of Magnesium-Tri Calcium Phosphate Composite Fabricated by Stir Casting
Abstract: Magnesium MMC is preferred in applications requiring high-quality materials and has replaced monolithic materials. Bio-implants traditionally used are titanium, steel, and nickel-titanium alloys, however, their removal necessitates surgery, which is costly and painful. While biodegradable 3D-printed implants are effective and eliminate the need for a second surgery, they remain expensive. After several studies to solve this issue, the development of biodegradable implants is considered. Magnesium possesses good biodegradable properties. An …

Machine Learning-Based Quantification of Polymer Structure Property Relationships for Predictive Material Design
Abstract: Polymer structures exhibit complex, hierarchical arrangements that strongly influence macroscopic properties, yet consistent quantification remains challenging due to nonlinear interactions and limited unified modeling strategies. Existing approaches inadequately capture generalized structure–property mappings across diverse polymer systems. This research aims to establish a machine learning-based quantification model for polymer structure–property relationships to support predictive material design. A Polymer Structure Property Dataset of 5,000 polymer samples includes structural descriptors and experimentally measured …

Assessment of Compressive Strength of OPC and PPC-Based Concretes Combined by Ultrasonic Pulse Velocity and Rebound Hammer
Abstract: In this study, non-destructive tests were performed on ordinary Portland cement (OPC) and Portland pozzolana cement (PPC) based concrete specimens, namely the ultrasonic pulse velocity (UPV) and rebound hammer (RN). A relationship is thus established between the NDT values and the compressive strength. A statistical regression analysis was performed between the compressive strength with UPV and RN values to obtain a best-fit relationship and correlation coefficients. To take into account …
