Chemical Diversity for Tailoring Negative Thermal Expansion

Qiang Li et al.

Summary: Negative thermal expansion (NTE) has been a prominent topic in solid-state chemistry and functional materials, and the response of a lattice to temperature is closely related to its structural features and physical properties. In recent years, significant progress has been made in the study of NTE compounds, but the intelligent design of NTE structures and efficient control of lattice thermal expansion remain challenging. Nevertheless, the diverse chemical synthesis routes offer numerous strategies for achieving desirable NTE behaviors and related properties.

Design of zero thermal expansion and high thermal conductivity in machinable xLFCS/Cu metal matrix composites

Xuelu Pang et al.

Summary: In this study, a multicomponent reinforcement with negative thermal expansion (NTE) was designed for metal matrix composites (MMCs) to achieve wide-temperature-range zero thermal expansion (ZTE), high thermal conductivity, and certain machinability. The thermal expansion coefficient of the resulting composite can be adjusted to nearly zero over a wide temperature range, and its thermal conductivity is significantly enhanced compared with the base material. This work provides valuable insights into the development of high-performance metal matrix composites.

Tailoring thermal expansion coefficient from positive through zero to negative in the compositional crossover alloy Ti50(Pd40Cr10) by uniaxial tensile stress

Yumei Zhou et al.

Summary: The precision control of thermal expansion is crucial for maintaining the shape of materials at different temperatures. By applying uniaxial external stress to a single material embedded with nanoclusters, the thermal expansion coefficient can be adjusted, as demonstrated in a prototype alloy. The tunable thermal expansion behavior is only observed in compositions between martensite and strain glass, providing a design recipe for new systems with similar behavior.

Feiran Shen et al.

Summary: The spin structure of a magnetic system is influenced by various exchange couplings, with pressure-driven changes in interatomic distance leading to the evolution of a new spin structure CyS-AFM(b). Under pressure higher than 4 kbar, abnormal changes in Mn(Fe)-Mn(Fe) distances can transform CyS-AFM(b) into a conical spiral ferromagnetic configuration.

Negative thermal expansion in magnetic materials

Yuzhu Song et al.

Summary: The review summarizes the progress in magnetic NTE materials from Invar alloys to newly discovered materials like Mn-based antiperovskites, Laves phases, La(Fe, Si)13, Mn3Ge, R2Fe17, R(Fe,V)12, and R2Fe14B (R = rare earth elements). The NTE properties of magnetic materials can be controlled by adjusting magnetic exchange interaction through methods like chemical substitution, nanocrystallization, external field, and interstitial atoms. The main mechanisms of NTE of magnetic materials, including order-to-disorder transition, change of local moment, metamagnetic transition, short-range magnetic ordering, structural phase transition, and coexistence of magnetic phases, are summarized.

Spinodal-modulated solid solution delivers a strong and ductile refractory high-entropy alloy

Zibing An et al.

Summary: A new strategy is demonstrated to achieve ductile BCC HfNbTiV by decomposing the BCC arrangement into two different phases via spinodal decomposition, resulting in chemical composition modulations and elastic strain on a length scale of a few tens of nanometers. The periodically spaced beta* with large lattice distortion is particularly effective in hindering dislocation movement, leading to strain hardening and enhancing plastic strain delocalization, ultimately achieving high yield strength and tensile strain to failure.
