Effect of C, Mn, Cr on Hardenability of Medium Carbon MnB Steel 228 Pitch Crawler Belt
As the quenched crawler belt manufactured by steel 40SiMn2, 35MnTiB and 30MnTiB ( C≥030% ) easily occurs micro-cracks that doesn' t meet the requirement of anti-fracture behavior, while the hardenability HRC J1.542. 5 〜 49. 0 and J13.017. 5 ~ 37.

Toughening β‐Ga2O3 via Mechanically Seeded Dislocations
β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...

Hardenability Calculation of 20CrMnTiH Gear Steel and Control of Narrow Hardenability Band
The calculation method of the nonlinear equation is used to calculate the hardenability of 20CrMnTiH steel, and it can only be corrected by the actual production data, and can be used to calculate and predict the hardenability accurately.

An epi‐intraneural interface is developed through in silico optimization and a novel tridimensional microfabrication pipeline. The device integrates penetrating and epineural contacts on a flexible substrate. Mechanical, electrochemical, and in vivo testing in rat and pig reveal robust implantation, low‐threshold activation, and site‐dependent ...

Switchable Supramolecular Adhesive by Tuning Interfacial Bonding and Modulus
The supramolecular adhesive (HyDiP) shows reversible adhesion and recyclability. In the dehydrated state, it is dense, stiff (E ≈445 MPa), transparent, and provides strong bonding with adhesion strengths up to 4.65 MPa. In the hydrated state, it becomes porous, soft (E ≈0.11 MPa), and detaches easily, enabling sustainable high‐strength applications ...
