“…Intragranular cracks are different from intergranular cracks, which are characterized by cracks starting from the inside of the grains and are a kind of cracks based on dislocations. 76 It has been discovered that Ni-rich materials exhibit significant lattice mismatch in the (003) crystal plane, resulting in the formation of eddy currents and distribution of stress on this plane. Additionally, the (003) crystal plane has a low formation energy for oxygen vacancies, making it susceptible to oxygen loss.…”

Nickel‐rich cathode is considered to be the cathode material that can solve the short‐range problem of electric vehicles with excellent electrochemical properties and low price. However, microcracks, lithium–nickel hybridization, and irreversible phase transitions during cycling limit their commercial applications. These issues should be resolved by modifications. In recent years, it has been favored by researchers to solve a large number of problems by combining multiple modification strategies. Therefore, this paper reviews recent developments in various modification techniques for nickel‐rich cathode materials that have improved their electrochemical characteristics. The summary of multiple modifications of nickel‐rich materials will play a guiding role in future development.

In this study, bulk nanocrystalline material was fabricated from Inconel 718 powder through a process of powder high‐pressure torsion (HPT) and subsequent annealing heat treatment. Numerous dislocations generated during the powder HPT process successfully produced bulk Inconel 718 with nanocrystalline grains during the post‐annealing treatment. In addition, the Inconel 718 exhibited additional strengthening contributions such as dislocation strengthening by high pre‐existing dislocation density and precipitation strengthening from randomly distributed precipitates. As a result of these strengthening effects, the Inconel 718 showed ultrastrong yield strength of 1.40 GPa and ultimate tensile strength of 1.53 GPa. Although the elongation of 12.0% did not indicate good ductility, the proposed Inconel 718 boasted improved mechanical properties compared to previous studies of Inconel 718 fabricated by various processing methods. The prepared Inconel 718 and its fabrication technique suggest the potential for manufacturing ultrahigh‐strength bulk nanocrystalline materials not only for Inconel 718 but also for various metallic materials using powder metallurgy.This article is protected by copyright.
