В статье проанализировано современное состояние и перспективы развития высокотемпературной дилатометрии. Приведены основные определения и понятия. Рассмотрены основные типы дилатометров, использующих контактные (механические) и дистанционные (оптические) методы измерений; описаны некоторые конкретные установки. Проанализированы ограничивающие факторы известных методов. Технический прогресс, продуцирующий материалы с новыми свойствами, требует создания подходов для исследования характеристик и возможностей применения таких материалов, а также, возможно, прогнозирования направлений современного материаловедения. Проанализированы технические приемы, которые могут обеспечить дальнейший прогресс в технике высокотемпературной дилатометрии. Представленный обзор обращен к исследователям – метрологам, материаловедам, физикам, работающим в области дилатометрии, а также к специалистам, создателям средств измерений.

The review analyzes the current state and prospects for the development of high-temperature dilatometry. Basic definitions and concepts are given. The main types of dilatometers using contact (mechanical) and remote (optical) measurement methods are considered; some specific installations are described. Limiting factors of known methods are analyzed. Technological progress, which produces materials with new properties, requires the creation of approaches to study the characteristics and application possibilities of such materials, as well as, possibly, forecasting the directions of materials science. Techniques that can ensure further progress in high-temperature dilatometry technology are analyzed. This review is addressed to researchers – metrologists, material scientists, physicists working in the field of dilatometry, as well as specialists who create measuring instruments.
