Phononic crystals (PCs) and metamaterials (MMs) have emerged as innovative platforms for manipulating acoustic and elastic waves through tailored microstructures. However, their adaptability to dynamic environments is limited due to the conventionally fixed properties after fabrication, leading to the growing demand for tunable and reconfigurable structures. Phase transitions offer a promising mechanism to enable significant variations in the properties of PCs and MMs. Nevertheless, a comprehensive review of the phase transition-enabled strategies is urgently needed to summarize current advancements and guide future developments. This review systematically assesses recent theoretical and experimental progress in phase transition-based PCs and MMs, focusing on material systems including shape memory alloys (SMAs), shape memory polymers (SMPs), ferroelectric materials, and liquid-solid phase-change materials (PCMs). Key mechanisms are elaborated, including martensitic transitions, glass transitions, ferroelectric phase transitions, and solid-liquid phase transitions in various PCMs. Building on these mechanisms, state-of-the-art design strategies for enabling active wave manipulation and novel functional behaviors, employing SMA-based systems, SMP-based systems, ferroelectric phase-change systems, and solid-liquid phase-change systems, are critically reviewed. In addition, advanced modeling and fabrication techniques to predict the material properties of PCMs and fabricate desi...
