In that context, the use of ferritic stainless steels has grown in recent years on account of its excellent relationship between corrosion resistance and cost, and a great option in substitution of austenitic stainless steels.

Abstract:
Through thickness microstructure and mechanical properties of defect-free electron beam welded 20 mm thick AISI 316L austenitic stainless steel has been investigated as a function of beam power. The weld microstructure is characterised by a columnar and equiaxed dendritic ferrite in an austenite matrix. The dendritic structure was finer at the bottom of the weld zone. A microstructural boundary called “Parting” was seen along the weld centreline. Tensile tests, using a digital image correlation technique, demonstrated that the highest strain was concentrated in the fusion zone. The bottom sect

Abstract:
High frequency corrosion fatigue crack propagation behavior of AISI 316L stainless steel was studied in 1M NaCl and 1M NaCl + 0.01M Na₂S₂O₃, under various anodically and cathodically polarized potentials, and dessicated air at 22°C and 1 atmosphere pressure. Constant load amplitude fracture mechanics techniques employing single edge notch specimens were used to assess the fatigue crack growth rate in the various environments. Unique specimen preparation procedures were developed which allowed near-threshold behaviors to be studied under gradually rising crack tip stress intensity conditions.

Abstract:
Austenitic stainless steels have a major problem during solution annealing or welding in the temperature range of 500-800 &deg<br>C due to the formation of chromium carbide, which causes chromium depleted areas along grain boundaries. This means that the structure has become sensitized to intergranular corrosion. Susceptibility to intergranular corrosion can be determined by means of destructive acid tests or by nondestructive electrochemical potentiokinetic reactivation (EPR) tests. The EPR test, which provides quantitative measurements, can be practiced as single loop or double loop. Single

Abstract:
Gas nitriding is known as a convenient process to improve the wear resistance of steel components. A precipitation-free hardening by low-temperature processes is established to retain the good corrosion resistance of stainless steel. In cases of thermal spray coatings, the interstitial solvation is achieved without an additional surface activation step. The open porosity permits the penetration of the donator media and leads to a structural diffusion. An inhomogeneous diffusion enrichment occurs at the single spray particle edges within the coating’s microstructure. A decreasing diffusion dept

Abstract:
Os aÃos inoxidÃveis austenÃticos (AIAs) sÃo largamente aplicados nas indÃstrias de alimentos, transportes nuclear, petroquÃmica devido à adequada combinaÃÃo de resistÃncia mecÃnica, conformabilidade e resistÃncia à corrosÃo. Dentre estes tipos de aÃo, destaca-se o AISI 301 por sua resistÃncia mecÃnica superior. Entretanto, este tipo de aÃo apresenta um dos piores desempenhos em termos de corrosÃo. Toda a resistÃncia à corrosÃo dos AIAs se baseia em sua camada de filme passivo contendo Cr203 que pode facilmente ser destruÃda em ambientes contendo cloreto. Neste trabalho, estabeleceu-se a meta d

Abstract:
O fresamento do aço inoxidável austenítico é um processo importante para a produção de peças em que se deseja alta resistência mecânica e à corrosão. No entanto, a usinagem desse material representa um desafio por suas características adversas ao corte. A alta taxa de encruamento e a alta dureza relativa fazem-no resistente ao corte, podendo gerar vibrações em diferentes faixas de frequência. Uma técnica importante ao processamento de sinais de vibração é a Transformada de Wavelet que permite analisar diferentes frequências do sinal através da subdivisão em aproximações e detalhamentos.

O uso da simulação via método de elementos finitos (MEF) tem sido de suma importância para o desenvolvimento de processos de conformação hidrostática de tubos (CHT). Sua utilização reduz o método de tentativa e erro na definição do processo e grandes ganhos de produtividade são auferidos. Neste trabalho, a simulação via MEF em conjunto com o desenvolvimento analítico existente na literatura foi utilizada para o desenvolvimento de um método projeto de uma ferramenta simples para a CHT em matriz aberta e para uso em prensa comum.

Os aços inoxidáveis austeníticos são materiais atrativos para serem utilizados em vários setores industriais que operam sob meios corrosivos, como por exemplo: indústria química, alcooleira, petroquímica, de papel e celulose, na prospecção de petróleo e nas indústrias têxtil e farmacêutica. Contudo, apresentam propriedades tribológicas pobres. No sentido de melhorar essas propriedades, como aumentar a dureza superficial, a resistência ao desgaste e a resistência à fadiga, vários métodos de tratamentos superficiais vêm sendo utilizados. Dentre eles, o mais eficiente é a nitretação por plasma. E

Abstract:
Austenitic stainless steels are widely used in the chemical, petrochemical and food-processing industries due to their excellent corrosion resistance and good mechanical properties. However, due to their inherent austenitic structure, they have relatively low hardness, as well as poor wear resistance and short fatigue life. Thermochemical surface treatments are used to improve the wear resistance, hardness and fatigue life. Austenitic stainless steels are difficult to carburise due to the tenacious Cr2O3 layer on the surface, although plasma and gas carburising have proven to be very effective

The results indicated that sensitized and unsensitized steel plates have the same fatigue crack growth characteristic in the air, so as the welds. Changing the testing environment from air into gaseous hydrogen, hydrogen enhanced crack growth occurred for all the specimens but to different degrees.
