Implants are inevitably subjected to stress corrosion, bringing serious challenges the controlled degradation of biomedical Mg alloys. It is worth studying corrosion cracking (SCC) behavior alloy and exploring with good SCC resistance for wide applications. In this work, as-cast as-extruded Mg-3Gd-1Zn-0.4Zr (GZ31K) alloys uniform were used investigate behavior. The GZ31K exhibited better mechanical properties than one mainly owing grain refinement uniformly distributed fine precipitates, possessed superior resistance. To clarify mechanism, slow strain rate tests assisted applied constant potentials via an electrochemical workstation. Accelerated anodic dissolution at polarization deteriorated due initiation pits micro-cracks. However, cathodic had no obvious effects on resistance, along both retarded accelerated hydrogen evolution. Stacking faults in capture containers reduce effect during polarization. These findings provide new insights into evaluation offer more opportunities explore by regulating dissolution.

Magnesium alloys are emerging as promising alternatives to traditional orthopedic implant materials thanks their biodegradability, biocompatibility, and impressive mechanical characteristics. However, rapid in-vivo degradation presents challenges, notably in upholding integrity over time. This study investigates the impact of high-temperature thermal processing on attributes a lean Mg-Zn-Ca-Mn alloy, ZX10. Utilizing rapid, cost-efficient characterization methods like X-ray diffraction optical microscopy, we swiftly examine microstructural changes post-thermal treatment. Employing Pearson correlation coefficient analysis, unveil relationship between properties critical targets (properties): hardness corrosion resistance. Additionally, leveraging least absolute shrinkage selection operator (LASSO), pinpoint dominant factors among closely correlated variables. Our findings underscore significant role grain size refinement strengthening predominance ternary Ca2Mg6Zn3 phase behavior. suggests that achieving an optimal blend strength resistance is attainable through fine grains reduced concentration phases. thorough investigation furnishes valuable insights into intricate interplay processing, structure, magnesium alloys, thereby advancing development superior biodegradable materials.

The high corrosion rate of magnesium alloys in body fluids represents a serious drawback for biomedical applications. Grain refinement through equal channel angular pressing (ECAP) processing seems to be quite promising overcome this issue. This work investigates the conditions depositing layered double hydroxides (LDHs) coatings coprecipitation and hydrothermal treatment on AZ31 alloy subjected 1, 2, 4 ECAP passes. Owing their tunable structure ion‐exchange capacity, LDHs have capability load release drugs. Synthesis is made by using two distinct synthesis times (30 min 12 h) then samples are examined light microscopy, scanning electron X‐ray diffraction. results show that LDH deposition strongly affected substrate microstructure. nucleation occurs screw dislocations emerging at surface substrate: fine homogeneous distribution crystals achieved if, addition nuclei distribution, diffusion occurs. condition favored 0002‐texture component. 1 pass with time 30 gives rise complete coating crystal morphology suitable medical

The aim of this work is to predict, for the first time, high temperature flow stress dependency with grain size and underlaid deformation mechanism using two machine learning models, random forest (RF) artificial neural network (ANN). With that purpose, a ZK30 magnesium alloy was friction stir processed (FSP) three different severe conditions obtain fine microstructures (with average sizes between 2 3 µm) prone extensive superplastic response. samples clearly deformed by boundary sliding (GBS) at temperatures. maximum elongations failure, well over 400% strain rate 10−2 s−1, were reached 400 °C in material coarsest 2.8 µm, 300 finest µm. Nevertheless, response decreased 350 due thermal instabilities coarsening, which makes it difficult assess operative such This highlights models considered, especially ANN model higher accuracy predicting values, allow determining adequately creep behavior including other possible scenarios.
