Fiberboard Made from Scrap Denim: Characterization of its Properties by Effective Bulk Modulus Elastography
Article describes how fiberboards from scrap denim were fabricated using two different resins, melamine urea formaldehyde (MUF) and polymeric methylene diphenyl diisocyanate (pMDI). Resin content and MUF-pMDI weight ratio were studied. Physical and mechanical tests determined the modulus of elasticity (MOE), modulus of rupture (MOR), internal bond (IB), thickness swell (TS), and water absorption (WA).

Laser powder bed fusion processing of a precipitation strengthenable FCC based high entropy alloy
Article describes how, while additive manufacturing (AM) of single-phase solid solution based high entropy alloys (HEAs) has attracted a lot of recent attention, such processing of precipitation strengthenable multi-phase HEAs has not been actively investigated. This becomes important since AM processing results in each layer experiencing rapid solidification followed by multiple heating-cooling cycles, mimicking in situ heat treatments, potentially influencing the phase evolution.

Room and Elevated Temperature Sliding Friction and Wear Behavior of Al0.3CoFeCrNi and Al0.3CuFeCrNi2 High Entropy Alloys
Article discusses how, in this study, processing–structure–property relations were systematically investigated at room and elevated temperatures for two FCC Al0.3CoFeCrNi and Al0.3CuFeCrNi2 high-entropy alloys (HEAs), also known as complex concentrated alloys (CCAs), prepared by conventional arc-melting. It was determined that both alloys exhibit FCC single-phase solid solution structure. Micro-indentation and sliding wear tests were performed to study the hardness and tribological behavior and mechanisms at room and elevated temperatures.
