“…In connection with the extend forging process, Araki et al (1985) scrutinized the effect of various extend forging methods due to a change in the density of powder sintered compacts, Rodic et al (1987) calculated proper operation conditions for the closing of internal voids in rolling or forging, and Sun and Guo (1987) introduced void closing parameters using the finite element analysis. In addition to the above-mentioned studies, Cho et al (1998) investigated the effect of different forging methods for extend forging on the hydrostatic stress or axial stress, and Banaszek et al (2004) studied die shapes and the distribution characteristic of the reduction ratio. A report was made by Nakasaki et al (2006) on the application of hydrostatic integral parameters to rolling.…”

“…In addition, many other handbooks, textbooks like Making, Shaping and Treating of steel (US steel), various seminars and conferences on forging have collated information on forging. Bauaszek et al [5] discuss about the homogenization of the values of local deformation within the entire cross section of forging. Theoretical studies have been performed in the plane strain deformation state.…”

The maraging steel are considered ultra-high strength due to its yield strength greater than 1400Mpa and are part of a set of advanced materials of interest for technological development, mainly for aeronautics and aerospace industry. For this purpose they should exhibit good toughness, fatigue resistance and acceptable weldability. Since the maraging steels are of higher cost we are intended to make the Medium Carbon Low Alloy Steel (MCLA) for the purpose of aeronautical and aerospace industry instead of Maraging steel as the cost of MCLA is comparatively less. An attempt is made to study on the basic properties of MCLA steels and Maraging steels by process modifications and comparing the results with that of the standard properties of the Maraging steel.

“…Além disso, foi estudada uma geometria industrial em escala reduzida, onde problemas de falta de material no último passe foram verificados, sugerindo correções na cinemática do processo e também na compensação de material através de uma geratriz maior. Banaszek [9,10] investigou geometrias côncavas que visam uniformizar a distribuição de deformações ao longo da peça, visando obter uma peça final livre de defeitos internos, concluindo que matrizes côncavas com partes convexas assimétricas, deformando a peça após um ciclo de 4 rotações de 90º ao longo de todo o seu comprimento, geram deformações homogêneas em todo o volume do forjado. Chen [11] apresenta estratégias de forjamento otimizadas quando utilizados ângulos de giro de 90º entre mordidas utilizando matrizes planas.…”

ResumoA investigação do comportamento de um mandril com diferentes diâmetros ao longo de seu comprimento no forjamento incremental em matriz aberta de eixos vazados para aerogeradores é estudada. Tem-se por finalidade a fabricação de um mandril que se adeque à peça forjada e atinja o formato proposto. Através do uso de simulações numéricas computacionais com o software Simufact.forming 12, e simulações com o material modelo plasticina, possíveis geometrias de mandris foram estudadas, variando a angulação na região de troca de diâmetros ao longo do comprimento. Foram estudados ângulos de 0º, 30º e 60º, analisando o comportamento da fluência do material na região. Palavras-chave: Simulação numérica; Geometria; Modelo de plasticina; Eixos. ANALYSIS OF INNER CONTOUR OF HOT FORGED HOLLOW SHAFTS AbstractThe investigation of the behavior of a mandrel with different diameters along its length in incremental open die forging of hollow shafts for wind turbines is studied. It has the purpose of making a mandrel that fits the forged part and reaches the proposed format. Through the use of numerical simulations with Simufact.forming 12 and simulation with plasticine models, possible mandrels geometries were studied by varying the diameters of the switch angle region along the length. Angles of 0º, 30º and 60º were studied, analyzing the behavior of the material flow in the region.
