Material issues are of paramount importance for the reliable and cost effective operation of gas turbine engines. Because of the high turbine temperatures, the materials degrade over time, which requires their repair or replacement. Rapid degradation or the inability to repair these complex materials results in excessively high operating costs. This paper concentrates upon the hot section components, because this is where the majority of turbine distress occurs. Superalloys, both nickel base… 

Advanced Materials used for different components of Gas Turbine

This paper presents a critical review of the existing literature of gas turbine materials and each plays an important role within the Gas Turbine Material literature and ultimately influences on planning and development practices.

Degradation of Gas Turbine Blades for a Thermal Power Plant

There are three stages of gas turbine blade in hot gas path (turbine section) of power generation gas turbine. Occurrences of wear and crack were observed on gas turbine blades in this section. The

Microstructural Changes during High Temperature Service of a Cobalt-Based Superalloy First Stage Nozzle

Superalloys are a group of alloys based on nickel, iron, or cobalt, which are used to operate at high temperatures ( > 540°C) and in situations involving very high stresses like in gas turbines,

Wear characteristics of commercial gas turbine components

Wear is one of the common degradations in a commercial gas turbine. A stainless steel grade 304 (SS 304) fuel nozzle and its collar made of nickel-based superalloy (Hastelloy X) are two vital

Analysis Of Hot Section Failures On Gas Turbines In Process Plant Service.

In-service failures of process plant gas turbines can have major economic consequences in terms of repairs and downtime. Following such an incident, steps need to be taken to avoid a recurrence. This
